The arrival of the world's biggest cargo ship in Britain is good news for Cambridge's Trinity College.

The vast vessel, the OOCL Hong Kong, docked at Felixstowe a few days ago to unload more than 20,000 containers.

And the land that much of the Suffolk port is built on is owned by the super-rich Cambridge college, which bought it for a relatively small sum - £54,000 - in the 1930s.

Felixstowe has since grown to become Britain's biggest and busiest container port - and the port's success is therefore good news for Trinity, which derives income from the land it sits on.

The land is called the Trimley Estate, and as well as the port, it includes farms, fishing lakes and a nature reserve. The college has also built the successful Trinity Distribution Park, as well as housing, shopping and community facilities.

The Port of Felixstowe is operated by Hutchison Ports UK, and OOCL Hong Kong is just one of 3,000 vessels that now use it every year.

A Port of Felixstowe spokeswoman said: "It has now just left, but we expect further visits later in the year."

Trinity, which has an endowment topping £1 billion, also owns the 999-year lease of the O2 Arena, which brings in rental income, and three years ago the college bought Dunsfold Park in Surrey for £50 million, which is the site of the BBC's Top Gear track.

Earlier this year, it was announced Trinity was going to lease three cottages and a disused squash court from the Cambridge Union Society, at a cost of £4.5 million, enabling the society to carry out a major renovation scheme.
